Specification of Letters Patent.

Patented Sept. 16, 1919.

Application filed. March 22, 1919. Serial No. 284,402.

To all whom it may concern:

Be it known that 1, CHARLES H, BOYLES, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Anchors, of which the following is a specification.

This invention relates to anchors constructed of reinforced concrete; and its object is to produce an efficient anchor of this type which may advantageously be used as a substitute for wrought or castmetal anchors.

A further object is to produce an anchor of inexpensive cost and of strong and durable construction.

To these and other ends, the invention consists in the novel construction, adaptation and combination of devices, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1, is an elevational View showing upon One side I the concrete structure and on the other side is shown the reinforcing framework to be embedded in concrete as indicated by dotted lines. Fig. 2 is an elevational view of the upper portion of the reinforcing structure for the anchor shank taken rectangular to Fig. 1. Fig. 3 is a similar view, rectangular to Fig. 1, of the lower part of the anchor. Fig. 1 is a sectional view through 4-1 of Fig. 1. In Figs. 2, 3 and 4: the outlines of the concrete embedding the reinforcing framework is represented by dotted lines. Fig. 5 is a perspective view of one of the frame members.

In said drawings, the reference numeral 5 desi nates the shank and 6 the arms of a four-fliike anchor consisting of concrete cast about a reinforcing or skeleton frame which is fabricated from iron or steel rods. The shank portion of said frame comprises two rods bent at substantially their midlengths to afford loops 7 engaging the anchor ring 8 and providing from each rod two clownwardly extending corner elements 9. These elements are connected by bends 9 with hooks 15 extending laterally, as at 11 and 12 (Fig. 4:) in converging directions at each side and disposed in planes which are inclined slightly upwardly.

As shown, the parts 11 terminate in ends 11 while the associated parts 12 extend to 100' 12 and thence returning terminate in 1 .2 which overlap the ends 1.1 the thereto by wire ties 21.

adjacent ends thereof being secured together by wire ties 13.

Seated upon parts 11 and 12 of the two abovesubscribed hook members are the side 18 and 18 of the respective members.

The members 18 are suspended from the hook elements 15 and 16 by spaced hanger straps 20 formed of rods and connected Straps 22 formed of suitably bent rods having their ends coupled by the wires 23 are employed to unite the elements 9 to which they are connected by means of wire ties 23 Supplementary to the members 18 are rods having upright stems 24: secured by tie wires 25 to one or more of the shank straps 22 and having at their lower ends arms 2 1 which are directed into the space between the upper and lower members of the frame at the front and rear of the same.

The above-described parts are assembled as shown, and an angular shaped flukeplate 26 is attached to the outer ends of the complementary hooks and ends of members 18 by means of bolts 27 extending within the various hook loops and apertures provided in the plates.

In operation, the reinforcing skeleton framework is placed within a suitable mold into which concrete is deposited to embed the same, except the fluke plates 26 whose upper and lower surfaces are respectively flush with the corresponding surfaces 6 and 6 of the anchor arms 6. These fluke plates serve to protect the points of the arms from being broken, and may be replaced when worn.

Except for said plates and a part of the ring 8 which protrudes from the shank, there is no metal exposed. Y

The various elements of the hookirlembars and the members is which are sabja cent thereto, are disposed to 'be in lines adjacent to and approximating the corners of the embedding concrete material. The hook members have their arm elements 15 integral with the shank elements, whereby strength and rigidity is afforded to the lateral arms.

The arm elements 16 at the front and rear, as shown, are connected by tie Wires to the hook members, and by extending between the remote ends of the anchor arms, are peculiarly eflicient to afford strength and rigidity to the longitudinally disposed arms. These arms are furthermore reinforced by means of the members 2a 2at whose stems are connected with the hook members-and have their parts 24F extend into-the concrete material of the respective anchor arms.

Reinforcingiframework thus constructed provides a skeleton which is peculiarly strong. and is adapted to withstand the strains to which the various parts of the anchor are subjected.

What I claim, is-

1. A- composite anchor havinga shank and arm elements-at one'end of the shank, skeleton frameworkformcd of interconnected rods, said frame having portions extending into both-the-arms and said shank, fluke plates bent to angular forms and secured to the extremities of the arm'portions of said frame, and a filling of cement within which said frame 'is embedded, -the outer surfaces of said arms in proximity to their points being flush with the-outer surfaces.

2. A. composite anchor having a shank and arm elements at one end of the shank, a ring at the other end ofthe shank, skeleton framework formed of interconnected rods, said frame having. portions extending into both the arms and said shank and connected to said ring, fluke plates bent to angular forms and secured to the extremities of the arm portions of said frame, anda-filling of cement within which saidframe isembedded, the outer surfacesof said arms iii-proximity to their points beingflush with the outer surfaces.

3. A composite anchor having shank and Copies of this patent may be obtained for-five cents each, by addressingthe arm elements, two sets of super-arranged rods extending into proximity of the outer ends of the respective arms and constituting a skeleton frame for the latter, the rods of each set being connected together within the respective arms, and a body of concrete Within which said frame is embedded.

4. A composite anchor having a shank and arm elements a skeleton frame composed of rods, a filling of cement embedding said frame, andangular shaped metal fluke plates provided at the points of the respective arms and into-which extend the arm elements of said 1 frame.

5. In a composite anchor, a skeleton frame having in the arm sections thereof two sets of rod members disposed at different elevations and terminating in looped portions adjacent tothe points of the respective arms, substantially horizontal connections uniting the members of the upper set of members, and substantially upright connections uniting the members of both sets thereof.

6. In a composite anchor, having a shank and a plurality of arms extending from'its lower end, a. skeleton frame having two sets of members disposed at different elevations, the upper of said sets having elements extending into both the anchor arms andthe shank, the lowest setof members being-located entirely Within the arms, and connections uniting the members ofboth sets of members.

7. In a'composite'anohor having a shank and a plurality of arms extending from its lower end, a skeleton frame having two-sets of members disposed at different elevations, the-upper of said'setshaving elements extending into both the anchor arms and the shank, the lower set of members being located entirely withinthe arms, substantially horizontal connecting the members of the upper setof members, andsubstantially upright connections uniting the members of both sets thereof.
